ANTHONY HUDOBA, 0F STRUTHERS, OHIO.

SELF-MOVING CRADLE.

Application filed October 12, 1921. Serial No. 507,360.'

To all whom it may concern:

I Be it known that ANTHONY HUnoBA, citizen of the United States of America, residing'at Struthers, in the county of Mahoning authorities injurious to, the health of the child. The principal object of the present invention is to obviate the above named defects and to provide a self-moving cradle in which a horizontally-reciprocating movemerit is imparted to the cradle body.

A' further object of the invention is to provide simple and efiicient mechanism for automatically actuating the cradle-body.

The novel features of the invention will hereinafter appear and finally be pointed out in the claim.

In the accompanying drawings, in which corresponding parts are designated by the same reference characters throughout,

Figure 1 is a top plan view of the base portion of the self-moving cradle.

Figure 2 is a side elevation of Figure 1.

Figure 3 is a top plan view of the cradle portion.

Figure 4 is a side elevation of Figure 3, also'showing a portion of the base portion of the self-moving cradle.

Figure 5 is a detail view.

By referring to Figure 2 it will. be seen that'the improved cradle is mounted upon wheels 1. These wheels support the entire cradle, and may be secured to depending legs'f2, which may carry any suitable frame structure for supporting the cradle portion of the device.

By referring to Figure 1 it will be seen that I have provided a support member 3, which may be a part of the frame work of the lower portion of the cradle. Mounted upon this support member 3 at a point 4 is a motor 5. This motor 5 may be an electric motor, or other suitable type of motor. Attached to this motor is a drive pulley 6, carrying a belt 7, functioning with a pulley 8 which is secured to a shaft 9. This shaft 9 is journaled in the frame portion of the device at points 10 and 11.

At point 12 there is secured a pulley 13 carrying a belt 14, which functions with a pulley 15, which is secured to a shaft 16. This shaft 16 is journaled to the frame portion of the device at points 17 and 18. This shaft 16 has ends 19 projecting outwardly beyond the frame portion of the device. Secured to these ends 19 are drive wheels 20 provided with wrist pins 21, which engage a ink 22, while the other end 23 is secured to a perpendicular actuatingbeam 24 by means of a bolt 25.

By referring to Figure 4 it will be seen that this perpendicular actuating beam 24 is secured at its upper end 26 to an arm 27.

By referring to Figure 3 it will be seen that this arm 27 is provided with a square opening 28 to function with the end 26 of the perpendicular actuating beam 24. This end 23 may be secured to the arms 27 in any desirable way so that there is no undesired looseness in the securing of the same.

By referring to Figure 1 it will be seen that the cradle 29 is slidably mounted upon a base 30, carrying a plurality of steel balls 31 confined in a race-way 32, so that the upper portion of the steel balls31 come in contact with an arched bearing member 33. This cradle portion of the device is secured in a slidable manner to the base portion at point 34 by means of an upturned U-shaped guide member 35. The upper portion of the guide member 35 is positioned above the arm 27 which is attached to the cradle 29.

By referring to Figure 5 it will be seen that I have provided a locking member 36, which is U-shaped in form, and when it is desired to secure the cradle 29 from accidental movement this locking member 36 is pushed into the openings 37 and 38.

In operating the device the motor 5 is put in motion, which gives the movement to the belt 7 functioning on the drive pulley 6 and pulley 8, thereby turning the shaft 9 and the pulley 13 attached thereto, causing the belt 14 to move the pulley 15, thereby turning the shaft 16.

By referring to Figure 1 it will be seen that the drive wheels 20 are secured to this shaft 16 and give motion to'the link 22, which actuates the perpendicular beam 24,

which in turn causes the cradle 29 to move in a horzontal andreciprocating movement.

It isunderstood that the pulley 15 may be reduced in size, or increased in size, in order to regulate the movement of the cradle.

What I claim is:

In a self-moving cradle, a base portion, a support member carrying a motor, a shaft secured to said base portion, a pulley mounted on said shaft and driven by said motor, a second pulley secured to said shaft, a second. shaft and a pulley attached thereto registering with said second pulley on first shaft, a belt functioning on saidpulleys, drive wheels attached to the end of second shaft, wrist pins secured to said drive wheels, link members secured to said wrist pins and to a vertical actuating beam secured to a cradle body portion, substantially as described for the purpose set forth.

In testimony whereof I afiix my signature.

ANTHONY HUDOBA.
